Web30 jul. 2024 · 14. It is the arrangement of electrons into shells and subshells that most concerns us here, so we will focus on that. We use numbers to indicate which shell an electron is in. As shown in Table 2.7.1, the first shell, closest to the nucleus and with the lowest-energy electrons, is shell 1. In 1913 Bohr proposed a model of the atom, giving the arrangement of electrons in their sequential orbits. At that time Bohr allowed the capacity of the inner orbit of the atom to increase to eight electrons as the atoms got larger, and "in the scheme given below the number of electrons in this [outer] ring is arbitrary put equal to the normal valency of the corresponding element." Using these and other constraints he proposed configurations that are in accord with t… Web2 jan. 2024 · Atoms Tend to Form Bonds Until Their Valence Electron Shell is Filled.
